IPC: C01G21/00
Filed: 1981-03-20
Granted: 1984-10-31
Abstract: Lead is separated from material containing lead sulfide, e.g. galena ore concentrate, by a substantially autogenous process involving establishing a pool of molten lead in a kettle, adding a metallic alkali metal, e.g. metallic sodium, to the molten lead in an amount sufficient to reduce the combined lead of the lead sulfide to metallic lead, adding the ore concentrate to the molten lead pool, and mixing together the metallic sodium, molten lead and ore concentrate. The sodium reacts rapidly and exothermically with the lead sulfide to reduce the combined lead of the lead sulfide to metallic lead and form sodium sulfide. The thus-liberated metallic lead reports in the molten lead pool, and a matte phase containing the sodium sulfide separates from the molten lead and forms on the surface of the molten lead pool. Lead sulfide from an excess of the ore concentrate, or other suitable added flux, which is usually added to the molten lead pool, serves to flux the sodium sulfide-containing matte phase to attain desired fluid and low melting characteristics of the matte phase. The process herein employs a kettle as the reactor, ordinarily the steel refining kettle of a lead refinery, is a low temperature process requiring temperatures above the melting point of lead but ordinarily not above 650 DEG  C., and does not discharge polluting SO2 into the atmosphere.

Filed: 1981-01-26
Granted: 1987-11-04
Abstract: A tractor locking differential (12, 18) is controlled by a solenoid operated hydraulic valve (34). The solenoid valve is in turn controlled by a logic circuit (36) which is responsive to signals received from a differential lock floor switch (32), application of brake lights (26) through the closing of a contact (28 or 30), and also from powering up the tractor. When the ignition (20) is turned on a flip-flop (50) within the circuit (36) will be cleared by action of a power up to clear circuit (58, 60, 64, 66) to dispose valve (34) in its unlocked position. After power up the operator can selectively lock or unlock the differential by application of momentary contact switch (32) which causes flip-flop (50) to toggle. When a brake light switch (28 or 30) is closed the flip-flop (50) will be cleared causing valve (34) to be disposed in its unlocked position.
